What NICE guidance and clinical trial data say about eligibility
The starting point for understanding how to get on Wegovy for weight loss is knowing what the clinical bar actually is. NICE's appraisal of semaglutide (Wegovy), TA875, recommends it for adults with a BMI of 35 or above and at least one weight-related condition such as high blood pressure, type 2 diabetes, or obstructive sleep apnoea, with lower BMI thresholds applying for some ethnic backgrounds under UK guidance. It also sets a maximum treatment duration of two years within a specialist service.
The weight-loss results that informed those recommendations came from the STEP 1 trial, a large randomised study published in the New England Journal of Medicine, in which participants taking 2.4mg semaglutide lost around 15% of body weight on average over 68 weeks alongside lifestyle support. That evidence base is why the medicine carries real clinical weight, and why prescribers take the assessment seriously. A BMI figure alone doesn't settle the question; a clinician looks at the whole picture before issuing a prescription.
One misconception worth gently setting aside: some people assume that because Wegovy is widely discussed, it must be easy to obtain. The clinical threshold exists precisely because this is a medicine with a specific licensed use, not a supplement anyone can pick up. Meeting the BMI criteria is a necessary starting point, not a guarantee.
The two routes to a Wegovy prescription in the UK
On the NHS, Wegovy is available through specialist weight management services, but waiting lists are commonly long, and TA875 requires the prescription to sit within a multidisciplinary service, which not every area has readily accessible. Our overview of NHS semaglutide access sets out how the NHS pathway works and who currently qualifies.
The private route bypasses the waiting list but not the clinical assessment. A regulated online pharmacy with a GPhC-registered prescriber on staff will take a clinical history, verify your identity, confirm your weight, and review whether treatment is appropriate, all before issuing a prescription. That assessment is a legal requirement, not an optional formality. At nume, our prescribers read every consultation personally on the day it comes in. The team behind the service is clinician-led, and clinical review sits at the centre of every order.
If you are already on treatment elsewhere and want to transfer, that is straightforward, though your new prescriber will want to see evidence of your current dose and recent clinical history before continuing.
How to verify any online pharmacy before using it
The MHRA has warned publicly about counterfeit weight-loss pens sold through social media and unverified websites. During 2025, enforcement operations seized roughly 20 million doses of illegally traded weight-loss medicines with an estimated street value of around £45 million, including a Northampton site producing fake tirzepatide pens. Fake pens have in some cases contained insulin, a serious risk. The MHRA's Yellow Card scheme allows anyone to report a suspected counterfeit seller, and the regulator encourages people to do so.
Before using any online pharmacy for a prescription medicine, check it on the GPhC register. The General Pharmaceutical Council maintains a public register of every legally operating pharmacy in Great Britain; you can verify a pharmacy's registration number at pharmacyregulation.org. nume's GPhC premises registration is 9012878, look it up. Red flags include sellers offering the medicine without a prior consultation, prices far below the typical private market, or discount codes tied to prescription medicines. A legitimate pharmacy does not offer those things.
If you want to explore clinics rather than online services, our guide to what to expect from the wegovy weight loss clinics covers what to look for in a physical setting.
